Growing Cyber Threat Landscape Leaves US Small Businesses Increasingly Vulnerable

Small and mid-sized businesses are facing an unprecedented surge in cyber threats, with half already hit by attacks and most expecting the risk to grow. Yet despite growing awareness, many organizations are still relying on ineffective or incomplete measures to protect themselves from future cyberattacks.

According to a new survey by cybersecurity platform Guardz, nearly half of small and medium-sized businesses (SMBs) have already faced a cyber incident, and 61% anticipate that these risks will continue to rise. Emerging threats such as AI-driven attacks, automated phishing schemes, and identity misuse are becoming increasingly prevalent.

While many SMBs recognize the importance of cybersecurity, only 34 percent have a formal incident response plan in place. This study found that 80 percent of SMBs with such plans avoided major damage during incidents, which proves that preparation is critical for minimizing impact.

“In 2025, SMBs are confronting the reality that cyber threats are no longer distant possibilities, but daily risks with the potential to disrupt or even destroy a business,” said Dor Eisner, CEO and co-founder of Guardz.

Fragmented security operations and hidden vulnerabilities

The most common weaknesses among SMBs include human error (45%), outdated technologies (42%), and the absence of formal security policies (32%). These vulnerabilities persist not because of a lack of intent but due to operational limitations, which leave businesses exposed to growing cyber threats.

Most SMBs still rely on basic security tools such as firewalls (58%) and spam filters (52%), and advanced measures like penetration testing (26%) and cloud security tools (30%) remain uncommon. Moreover, cybersecurity responsibilities are often scattered across teams, which creates blind spots and inefficiencies that increase vulnerability. Breaches now often result in six- or seven-figure losses, with extended recovery cycles and operational paralysis.

The growing role of Managed Service Providers

According to Guardz, fear of cyberattacks (52%), compliance requirements (36%), and the desire to lower insurance premiums (33%) are key factors driving SMBs to seek Managed Service Providers (MSPs). Businesses can partner with MSPs to close critical gaps in areas such as employee training, policy enforcement, continuous monitoring, and incident response.

Practical steps to strengthen cyber resilience

To strengthen cybersecurity resilience, organizations should prioritize a proactive and layered security strategy. This includes implementing advanced tools such as AI-driven threat detection, identity governance, and continuous monitoring to counter evolving risks. Moreover, regular employee training and strict policy enforcement are important to reduce human error. It’s also advised to adopt formal incident response plans to significantly minimize damage during breaches.

Additionally, businesses should invest in integrated solutions and partnerships to overcome operational limitations. MSPs can provide expertise in areas (like penetration testing, cloud security, and compliance management) to ensure comprehensive coverage. Organizations can combine technology, governance, and collaboration to close critical gaps and stay ahead of emerging threats.
